... To achieve strong authentication security, we ensure that any difference being introduced into the state would result in a particular difference with sufficiently small probability so that it is difficult to launch a ... See full document

... The experiments were able to perform when there are less than 7 unknown variables in the internal state. Thus this will require an exhaustive search of 2 286 over the internal state. The total complexity of this attack ... See full document

... We emphasize that the above counterexample does not imply that common OAE1-secure schemes with expansion 𝜏 fail to be OAE2-secure with expansion (0, 𝜏 ) once reconceptualized and restricted. Such a determination would ... See full document

... Our specification can be seen as a generalization of both the XE(X) construction of Rogaway [74] and the tweakable blockcipher from Chakraborty and Sarkar [19] to the permutation-based setting. While Rogaway limited ... See full document

... Recently, Handschuh and Preneel [39] showed that, compared to block cipher based, MACs based on universal hash functions have a key-recovery vulnerability. In principle, a small probability of successful forgery ... See full document

... Third party cryptanalysis. An independent cryptanalysis of ForkAES by Banik et al. showed, that a round-reduced version with 9 rounds (instead of full 10 rounds) can be attacked with practical complexity [3]. More ... See full document

... Another direction of GC was put forward by Sarkar [18], where a stream cipher is used for encryption and a universal hash function is used for authentication. In [18], a total of 17 AEAD/DAEAD schemes are ... See full document

... Two later variants of the OCB mode have been proposed in [51, 40]. Currently, the version appearing in [40] is the “official” OCB mode of operation and is sometimes also denoted as OCB3. AE(AD) modes of operations having ... See full document
